Screw/Threaded connection
Hello to all
I am fresh to plastic part design, especially regarding the about the ways parts should or could assemble each other.
At this particular moment I am most interested in screw/thread joints, like a cap for the bottle, cover, or two parts assembled togheter by "screw joint". By this I do not mean parts joint by screws - >

I can find the mechanical equation for this issue but I missed general info.
Can you tell me what, where and why?
* Which type of thread fits best for plastic application?
* how to develop best number of rotation for "nut part"?
* what should be the height of "nut part"
please follow thread types introduced in attached picture
